Description

Die erfindungsgemäße Lösung gestattet beispielsweise die freie Bewegung von Niederholern in Trimmeinrichtungen, zum Beispiel Großbaumtrimm, in ihrer einen Laufrichtung beim Dichtholen mittels einer Winde und ein selbsttätiges Belegen des Niederholers nach dem Dichtholen Infolge der durch den Qroßbaum bewirkten Zugspannung. Durch Schwenken des Bedienhebels werden der belegte Niederholer gelöst und dadurch ein Fieren des Großbaums ermöglicht. In gleicher Welse ist die Klemmvorrichtung für Fallen zum Setzen und Niederholen von Segeln sowie für Schoten zum Dichtholen und Fieren der Segel geeignet.The solution of the invention allows, for example, the free movement of Niederholern in trim devices, such as boom trimming, in their one direction when Dichtholen by means of a winch and an automatic occupation of the Niederholers after the Dichtholen due to the caused by the Qroßbaum tensile stress. By pivoting the control lever, the occupied Niederholer be solved, thereby allowing a fieren of the boom. In the same catfish the clamping device is suitable for traps for setting and lowering of sails as well as pods for sealing and fetching the sails.

Fig. 1 shows the clamping device according to the invention in a sectional view in a position which the free movement of the Rope 1 permits. Shown are one of the two side plates 2, an operating lever 3 with its pivot point 4 and rollers 5 for Guide the rope 1 and a rack 6.

Fig. 3 shows a plan view of the clamping device with the side plates 2, the Bedieihebel 3, consisting of two Side bars 7, between which the rollers 5 are mounted, serving as a fulcrum <of the operating lever 3 axis and the Tooth bar 6. The rope 1 is omitted in this Darstellnn j the better overview. 4 shows a variant of the clamping device with two toothed strips 6. The function of the clamping device is the following: When a trimming on the rope 1 in the one, in Fig. 1 indicated by an arrow running direction a tensile stress

ausgeübt, beispielsweise mit Hilfe einer Winde zwecks Dichtholens des Großbaums, wird der Bedienhebel 3 mit seinen Rollen 5 durch das Seil 1 derart um seinen Drehpunkt 4 geschwenkt, daß das Seil 1 von der Zahnleiste 6 abhebt und eine freie Bewegung des Seils 1 gewährleistet !st. Da die Zahnleiste 6auf der von dazugehörigen Rolle 5 beim Schwenken beschriebenen Kreisbahn angeordnet ist, geschieht das Abheben des Seils 1 von der Zahnleiste 6 in einer zum Seil 1 radialen Richtung. Dadurch tritt während des Abhebens keine Längsbewegung des Seils 1 in bezug auf die Zahnleiste 6 ein, wodurch ein Verschleiß vermiedenexercised, for example by means of a winch for the purpose of Dichtholens the boom, the operating lever 3 is pivoted with its rollers 5 through the rope 1 about its pivot point 4 that the rope 1 lifts from the rack 6 and ensures a free movement of the rope 1! st , Since the toothed bar 6 is arranged on the circular path described by the associated roller 5 during pivoting, the lifting of the cable 1 from the toothed bar 6 takes place in a direction radial to the cable 1. As a result, no longitudinal movement of the rope 1 with respect to the rack 6 occurs during take-off, thereby avoiding wear

When the tension in the one direction decreases, an automatic covering of the rope 1 then occurs. If a Tensile stress in the other, indicated in Fig. 2 by the further arrow running direction is effective, for example

durch die Zugspannung in dem Niederholer des dichtgeholten Großbaums. Hierbei wird durch die Zugspannung in der entgegengesetzton Richtung der Bedienhebel 3 mit den Rollen 5 in der anderen Schwenkrichtung derart um seinen Drehpunkt 4 geschwenkt, daß die eine der Rollen 5 das Seil 1 auf die Zahnleiste 6 preßt. Der Andruck des Seils 1 auf die Zahnleiste 6 um so stärker, je größer die Zugspannung in der anderen Laufrichtung ist. Die Zahnleiste 6 ist der äußeren Krümmung des Seils 1 angepaßt, so daß der Andruck und der Reibwert gleichmäßig über die Fläche der Zahnleiste 6 vorteilt ist. Die spitzen Erhebungen der Zahnleiste 6 graben sich auch hier nur in radialer Richtung in das Seil 1 ein, wodurch auch in diesem Fall das Auftreten vonby the tension in the downhaul of the densely hauled boom. Here is pivoted by the tension in the entgegengesetzton direction of the operating lever 3 with the rollers 5 in the other pivoting direction about its pivot point 4 that one of the rollers 5, the rope 1 presses on the rack 6. The pressure of the rope 1 on the rack 6 the stronger, the greater the tension in the other direction is. The toothed bar 6 is adapted to the outer curvature of the rope 1, so that the pressure and the coefficient of friction is evenly over the surface of the toothed bar 6 advantage. The pointed elevations of the rack 6 dig here also only in the radial direction in the rope 1, whereby in this case, the occurrence of

Wear is avoided. To solve the busy condition, if the example used here for the fieren of the boom, it is sufficient, the operating lever. 3

Location in which a free movement of the rope 1 in both directions is possible. On the representation of a lock of the Control lever 3 has been omitted for the sake of clarity. On the other hand, there are doubts about the appropriateness

Field of application of the invention

The invention relates to a clamping device for ropes euf sail vehicles, especially for covering the current Guts on seagoing yachts.

Characteristic of the known state of the art

Known is a clamping device for covering the current Guts on sailing vehicles, such as the traps and Schoter., Which is arranged to several juxtaposed in a row. In each case between two side plates, a bottom part with a series of protruding teeth, a one-armed pivoting clamping lever with a corresponding row of protruding teeth and a pivotable operating lever are included. A spring presses the clamping lever with its row of teeth against the row of teeth of the bottom part, that a running between the two rows of teeth on movement in one direction leads to jamming of the clamping lever and movement in the other direction to a release of the clamping lever. By moving the operating lever, the clamping lever can be forcibly released and locked in the first position, cf. U.S. Patent 4,462,011; B 63B- 21/08.

As with most previously known clamping devices also acts here the serious disadvantage that the so-called self-clamping is achieved by digging the teeth against the tensile force in the rope when a tensile force in the occupied state, for example, by the weight of a set sail is transferred to the tensile force on the teeth on the jammed part. This represents a significant stress on the rope, especially in an unavoidable slippage of the rope in clamping device. In a forcibly brought about in this state releasing the clamping lever, the teeth perform a further movement against the tensile force and are torn out simultaneously in the radial direction au3 the rope. However, this leads to heavy wear in connection with a necking of the rope, whereby the documents in the clamping device is increasingly unreliable and the risk of tearing of the rope grows.

Object of the invention

The aim of the invention is to reduce the wear of the ropes when documents by means of a clamping device, without sacrificing a safer and easier to use is to be accepted.

Presentation of the nature of the invention

The invention has the object zi reasons, with a clamping device for ropes, which is arranged in several juxtaposed and wipe two side plates a pivotally mounted control lever to make so that both the documents and when loosening the terminals used for clamping means only in the radiator direction be moved to the rope. According to the invention this object is achieved in that are mounted on the projecting between the side plates end of the operating lever in the pointing to the pivot point of the operating lever and in each direction of the rope corner points of a triangle rollers around which the rope is meandering, and that in the pivoting direction on at least one of the orbits described by the rollers when pivoting the operating lever one of the outer curvature of the guided around the rollers rope racks between the side plates is attached.

Advantageously, the operating lever consists of two side rails, between which the rollers are mounted. In a simplified embodiment, a plurality of control levers are mounted with the rollers between two side panels with mutual spacing.
